solana-labs/example-helloworld

Hello world example on Solana that increments a greeting counter stored in an account, in both Rust and C.

It's the official Solana hello-world template, not a hackathon submission: zero originality.

Verdict

This repo is the official Solana Labs hello-world example: a Rust/C program that increments a counter in an account, paired with a TypeScript client Official Solana Labs hello-world template description. It is not an original hackathon submission, an authenticity red flag that caps technical credit despite adequate tests, CI, and clean structure Authenticity red flag: template clone, not original work. Against the corpus, originality is a textbook false_gap: the mechanic is a known tutorial, so no genuine competitor exists, though the closest general match, Solana Buildpack, sits at only 0.056 . Winner-cohort DNA in this space skews toward oracle, lending, tokenization, and stablecoin primitives built with Anchor; this repo touches none of them, and the best winners-only match, IDL Space, is a mature debugging tool worlds beyond a counter demo . The one bright spot is momentum: 958 stars, 279 commits, and 41 contributors across four years of real maintenance GitHub metadata: 958 stars, 279 commits, 41 contributors. Next move: replace the tutorial mechanic entirely with a genuine on-chain product before resubmitting; as-is this cannot be presented as hackathon work.

Winner DNA

  • Uses Anchor framework: missing

    Repo uses raw Rust and C programs; 43/158 (27.2%) of cohort winners build with Anchor

  • Addresses a core DeFi/financial primitive (oracle, lending, tokenization, stablecoins): missing

    Repo is a counter-increment demo with no economic logic; these four primitives cover 38.7% of winner share combined

  • Targets DeFi traders or dapp builders with a working product: missing

    Target users are generic 'solana developers' learning the SDK, not the DeFi traders (13.9% of winners) or dapp developers (10.1%) segments winners actually serve

  • Uses Rust plus TypeScript client stack: present

    Matches the majority stack pattern (Rust 48.1%, TypeScript 22.2% share among winners)

  • Original, hackathon-conceived idea rather than a known template: missing

    Explicitly flagged as the official Solana Labs example repo, not original hackathon work
